Previous research has suggested a connection between coal - burning and the Sahel drought, but this was the first study that used decades of historical observations to find that this drought was part of a global shift in tropical rainfall, and then used multiple climate models to determine why.
When in January rainfall was double the expected average over wide areas, many people made cautious links between such extreme weather and global climate change.
So if you think of going in [a] warming direction of 2 degrees C compared to a cooling direction of 5 degrees C, one can say that we might be changing the Earth, you know, like 40 percent of the kind of change that went on between the Ice Age; and now are going back in time and so a 2 - degree change, which is about 4 degrees F on a global average, is going to be very significant in terms of change in the distribution of vegetation, change in the kind of climate zones in certain areas, wind patterns can change, so where rainfall happens is going to shift.
Significant changes in tree cover in Eurasia could cause an energy imbalance between the Northern and Southern Hemispheres, shifting the entire global circulation of the atmosphere, including the location of rainfall in the tropics.»

These assumed that the largest decreases in rainfall would be in winter and spring (decreases of 5 % and 11 % between 1990 and 2030 on the low and high global warming scenarios respectively), but rainfall was fractionally HIGHER in winter / spring in the more recent period (1995 - 2006) than in the previous 11 - year period.
In summer and autumn the CSIRO projections were for smaller decreases in rainfall than in winter and spring, but the observed change was a substantial decrease: in fact, as large a decrease between the successive 11 - year periods as CSIRO projected on the high global warming scenario over the 40 - year period from 1990 to 2030.
... incomplete and misleading because it 1) omits any mention of several of the most important aspects of the potential relationships between hurricanes and global warming, including rainfall, sea level, and storm surge; 2) leaves the impression that there is no significant connection between recent climate change caused by human activities and hurricane characteristics and impacts; and 3) does not take full account of the significance of recently identified trends and variations in tropical storms in causing impacts as compared to increasing societal vulnerability.
The activists say our influence on climate is evident in «altered rainfall patterns,» but in this they are at odds with their fellow - activists at the ill - fated Intergovernmental Panel, whose special report on extreme weather (2012) and whose fifth and most recent (2013) Assessment Report on the climate question find little or no evidence of a link between our industries and enterprises on the one hand and global rainfall patterns on the other.
«The authors write that «the El Niño - Southern Oscillation (ENSO) is a naturally occurring fluctuation,» whereby «on a timescale of two to seven years, the eastern equatorial Pacific climate varies between anomalously cold (La Niña) and warm (El Niño) conditions,» and that «these swings in temperature are accompanied by changes in the structure of the subsurface ocean, variability in the strength of the equatorial easterly trade winds, shifts in the position of atmospheric convection, and global teleconnection patterns associated with these changes that lead to variations in rainfall and weather patterns in many parts of the world,» which end up affecting «ecosystems, agriculture, freshwater supplies, hurricanes and other severe weather events worldwide.»»
Composite analysis of global sea surface temperature during unusually wet and dry years also suggests a linkage between reconstructed rainfall and ENSO.
The statistical forecasting methods are based on empirical relationships between rainfall over specific parts of the GHA and some global / regional / local climate system indices.

I would suggest that in fact, different parts of the globe may respond differently and that there is no simple global correlation between sunspot numbers, temperature and rainfall.
* «UK rainfall shows large year to year variability, making trends hard to detect» * «While connections can be made between climate change and dry seasons in some parts of the world, there is currently no clear evidence of such a link to recent dry periods in the UK» * «The attribution of these changes to anthropogenic global warming requires climate models of sufficient resolution to capture storms and their associated rainfall.»
